SHEAFI-C'ARRIER.

SPECIFICATION forming part of Letters Patent No. 538,009, dated April23, 1 895. Application filed September 16,1886. Serial No. 213,652. (Nomodel.)

To all whom it may concern.-

Be it known that 1, WILLIAM WORTH BUR- SON, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful sheaf-Carrier, of which thefollowing is a specification.

My invention relates, first, to an attachment to harvesters whereby thesheaves when bound may be carried until a sufficientnumher have beenaccumulated and then deposited on the ground by the action of thedriver;

second, the dumping process may be done antomatically, when an agreedupon number have accumulated on the carrier; third, the dumping maybeautomatically accomplished by contact with the sheaves dropped on theformer round; fourth, the carrier folds out of the way of stumps, trees,gate posts, 850., auto-' matically, that is, without the attention ofthe driver; fifth, a shelled grain attachment is added whereby theshelled grain may be saved. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure 1 is a frontelevation, showing also parts of the binder and harvester. Fig. 2 is aside elevation. Fig. 3 is a plan view. The full lines show the carrierin position to receive the sheaves. The dotted lines show an elevationof the carrier folded horizontally, as in passing an obstruction. Fig. 4shows the carrier folded and turned in a vertical position. Fig. 5 is adetail of the counting attachment to the carrier. Figs. 6 and 7 showbelaying stop C. Fig. 8 is a front elevation enlarged from Fig. 1, thearm F being partly removed. Fig. 9 is a plan view of carrier platform.Fig. 10 is an end view elevation of Fig. 9. Fig. 11 is a section of Fig.5 on line a: 00.

Similar letters of reference denote the same parts throughout theseveral views.

In the drawings, Figs. 1, 2, 3 and 8, A is a part of the harvester frameor an extension therefrom, and A also a part of the harvester frame, theformer supporting the vertically pivotedbearer B, the upper end of whichhas a horizontal sleeve forming a support for the oscillating arm C inconnection with the belaying stop 0. To thearm C are hinged the supportsD, D, onwhich are secured the boards or pieces E, E, E E The trippingarm F has fingers reachingdown ward, adapted to engage the sheavesdropped on the former round. It has the runner F and arm F andconnecting rod F to be more fully described farther on. F is a supportfor F.

G is a flexible support for the rear end of the carrier attaching arm Dand ext-ending to the driver, not here shown. The spring G is adapted tobalance the weight of the carrier as desired.

C is a stop block on G, in which the latch G3 engages being held inposition by a spring G His a canvas under the receiving pieces E, Eadapted to save the shelled grain, (Figs. 9 and 10.)

I is a ratchet wheel, in this case with twentyfour teeth, upon onesurface in which is an operating pawl M.

I is a loose sleeve on. I having the pawl I operating in a notch of I.

I is a cam elevation on I.

I is a keeper for rope J and sleeve I.

J is a cord extending from the sleeve 1' to thespring J connected withthe harvester frame.

J is a cord extending-from the sleeve 1 to the reach of the driver.

K is an arm extending from the needle shaft, or may be the needle itselfwhen the construction will so admit of it.

L connects K with the arm M, upon which is the pawl M.

N is a right angled lever, one end of which I the - The connectiontherewith being so well understood is not-hereshown.

T is the ejector; T the rod connecting it with the packer P, Figs. 1, 2and 8. The construction of my improved sheaf carrier will be furtherexplained in connection with the description of the operation of thesame.

The rod C, which is conveniently made of gas pipe, is supported in asleeve on the upper end of the piece B which gives it freedom for twomotions. It extends through the sleeve in B to a stop catch C whichholds it in a recess with sufficient force for ordinary work, but willallow it to pass out and turn backward in B when meeting with sufficientresistance. This saves the necessity for removing the carrier in passingobstructions, as also the liability of breakage when striking againstsuch unobserved. The supports D, D are pivoted to O and adapted to foldclose to it.

The pieces E E E E may be made'of boards, or sheet metal. In the lattercase'a rod could be run in one edge to stiffen it. I prefer to have themoverlap a little the better to facilitate the folding process. Thepieces E, E, E E are fastened each to the pieces D, D, along one edgeonly of each piece bya pivoted fastening, which fastenings should beparallel throughout the several pieces. \Vhen thus attached they willfold together as shown in Fig. 4, each upper piece extending fartherback than the one next under it. It will be seen that the pieces D, D,fold alongside of O, and that the pieces E, E, E E fold one above theother, except that the upper piece is in each case farther back endwisethan the one directly under it. A cord attaching the rear end of D andextending over suitable friction pulley guides to a lever in reach ofthe driver gives means for operating the carrier. This part of themechanism is so well understood that I have not thought it necessary toillustrate it. A spring is conveniently attached to counterbalance theweight of the carrier.

When the carrier is constructed as just described it is ready to receivethe sheaves from the binder, and when a suflicient number hasaccumulated the driver releases the cord G, when the automaticattachment is not used which permits the rear end of the carrier to dropand the sheaves are thereby left on the ground, and on each succeedinground it is desirable to drop the sheaves opposite, the better tofacilitate the shocking.

To save the driver the trouble of observing the sheafcarrier and dumpingthe sheaves at the proper time, I have provided a device foraccomplishing the same, automatically, shown in Figs. 1, 2, 8 5, and.12. This device consists substantially of a drum revolved by a ratchetoperating a trip lever, operating to release the catch holding thesupporting cord. The drum I is supported on the harvester frame. Lever Mhas a pawl M operating in the ratchet, to turn the drum. Lever M isoperated by arm K, through the connecting rod L. At each movement oftyingthe sheaf, leverK revolves the drumIuntilthe cam block 1 tripslever N, which acting through connecting rod N, releases catch G andthereby dumps the sheaves.

It is desirable to control the number of sheaves dropped in a place.This is done by moving the controlling rod L in the holes in lever M.The nearer the pivoted pointof said lever the connection is made thegreater the movement of the pawl and hence the fewer sheaves will needto be tied to revolve the drum and the farther from the pivot the slowerthe movement of the drum and hence the more sheaves would be boundbefore the trip cam 1 would reach the trip lever N. When the carrier istripped automatically as just described an agreed upon number of sheavesmust be had before they will be dropped. This is not always satisfactoryand hence it is desirable to have the dumping under control of thedriver. To meet this requirement the sleeve 1 is put on the drum I. Thissleeve has a pawl '1 ,resting on a part of drum I, which has one catchonly corresponding to the trip cam 1 A cord J is attached to sleeve 1and extends to the driver. It will be seen when cord J is drawn, thepawl I will find the notch in drum I no matter in what partof itsrevolution it may be and turniugit until trip cam I acts upon trip leverN, trip the carrier without regard to action of ratchet lever M, andthat the tripping devices will be in proper shape to repeat theoperation. When the driver releases cord J, spring J brings the sleeveback one revolution to its original position, ready to act again whendesired.

It is desirable to drop the sheaves opposite each otherin Windrows. Inthe plan jnstgiven, this would not necessarily be done without somemeans of correcting it. To obviate this difficulty trip rake F havingthe downwardly projecting teeth a, a, a, a, is adapted to come incontact with the sheaves dropped in the former round and acting throughcrank F and rod F releases the latch G without regard to theotherdevice.SincethetriprakeFextends so far from the carrying wheels it is effectedby the roughness of the ground. To overcome this difficulty the rake armis jointed over the carrier support B both vertically and horizontally,thereby permitting the tripping device to swing with the carrier infolding, and to rest on the curved runner or shoe F by which it will beguided a proper height above the ground without regard to the positionof the wheels. These devices can be used together or separately, or thecarrier can be operated entirely under the control of the driver. Theejector T is adapted to act upon the bound sheaf where the dischargearms have moved itout of the place in which it is tied.

It has not been practical heretofore to use a sheaf carrier in badlytangled grain, the discharge arm S, (Fig. 1,) frequently becomingentangled in the grain and thereby failing to properly discharge thesheaf. This is especially the case when a sheaf carrier is used. Theejector T moves the sheaf away from the discharge arm and well out uponthe sheaf carrier from which it can be dumped, enabling the latter to beused in conditions of grain heretofore impracticable. This ejector Tmoves in a guide track T fastened to the' binder frame. It is operatedby the rod T? connecting it with the packer P thereby giving it areciprocating movement.

The operation of binding will generally shell more or less grain whichhas heretofore been wasted. To save this grain I place a canvas bottom Hon my carrier adapted to catch and hold the shelled. grain. The canvasmay extend somewhat back of the lower board Figs. 9 and 10 or there maybe openings S S in the upper surface of the carrier to permit thepassage of the grain. One side of the canvas should be fastened so as topermit the folding of the carrier, as with rings w, 00, m, w, held on arod D The other side may be fastened rigid Figs. 9, 1'0 and ll.
